Lesson One provides professional development that helps public, private and charter schools establish and design themselves for implementing a School Cultural Development Ecosystem. The ecosystem provides a process to help teachers, administrators, and parents seamlessly integrate initiatives including PBIS, Restorative Justice, common core, STEAM, RtI, etc. We integrate social and academic skills through our evidence-based practice for mental health.

Lesson One was twice featured by NBC in Los Angeles for its work promoting mental health in schools as a way to help prevent tragedies like those in Isla Vista, CA, Newtown, CT and others like it around the country and for its role in providing an ecosystem for social and academic success at school, home and community.

Michael Ryan, co-author of Lesson One: The ABCs of Life, wrote the following in
the book’s preface:

"Lesson One is the culmination of a long and exciting scientific project. Like the researchers who spent years learning how to prevent polio or cure smallpox, Jon Oliver has devoted his life to studying how people learn--or don’t learn--the lessons that will
equip them for the rest of their lives. Gradually, over many years of honing and changing, the ABC's of Life was born….Changing our culture has been the aspiration of humanity for as long as history has been recorded: Shakespeare, Emerson, and
Tennyson all wrote about finding a better world. Lesson One is changing lives, one child at a time. Lesson One can dramatically change our culture by expanding its reach and bringing its message to a nation in need."
